The Aspeed SoCs have a dual boot function for firmware fail-over
recovery. The system auto-reboots from the second flash if the main
flash does not boot sucessfully within a certain amount of time. This
function is called alternate boot (ABR) in the FMC controllers.
On AST2400/AST2500, ABR is enabled by hardware strapping in SCU70 to
enable the 2nd watchdog timer, on AST2600, through register SCU510.
If the boot on the the main flash succeeds, the firmware should
disable the 2nd watchdog timer. If not, the BMC is reset and the CE0
and CE1 mappings are swapped to restart the BMC from the 2nd flash.
On the AST2600, the ABR registers controlling the 2nd watchdog timer
were moved from the watchdog register to the FMC controller and the
FMC model should be able to control WDT2 through its own register set.
This requires more work. For now, add dummy read/write handlers to let
the FW disable the 2nd watchdog without error.

It unifies the errors reported by the Aspeed SMC model and also
removes some use of ctrl->name which will help us for the next
patches.

There is no real reason to use this name. It's simply nice to have in
the monitor output but it's a burden for the following patch which
removes the AspeedSMCController structure describing the controller.

AspeedSMCClass. Move all attributes under the class and adapt the code
to use class attributes instead.
This is a large change but it is functionally equivalent.

There is no need to keep a reference of the flash qdev in the AspeedSMCFlash
state: the SPI bus takes ownership and will release its resources. Remove
AspeedSMCFlash::flash.

AspeedSMCFlash::size is only used to compute the initial size of the
boot_rom region. Not very useful, so directly call memory_region_size()
instead.

AspeedSMCFlash is a small structure representing the AHB memory window
through which the contents of a flash device can be accessed with MMIOs.
Introduce an AspeedSMCFlash SysBusDevice model and attach the associated
memory region to the newly instantiated objects.

This simplifies the reset handler and has the benefit to remove some
"bad" use of the segments array as an identifier of the controller model.

The AST2400 SPI controller has a transitional HW interface and it
stores the address width currently in use in a different register than
all the other SMC controllers. It needs special handling when working
in 4B mode.
Make it clear through a class handler. This also removes another use
of the segments array.

Introduce an AspeedI2CBus SysBusDevice model and attach the associated
memory region and IRQ to the newly instantiated objects.
Before this change, the I2C bus IRQs were all attached to the
SysBusDevice model of the I2C controller. Adapt the AST2600 SoC
realize routine to take into account this change.
